[ Upstream commit 97c318bfbe84efded246e80428054f300042f110 ]
cxl_pmem.ko uses memory_add_physaddr_to_nid() but ia64 does not export it,
so this causes a build error:
ERROR: modpost: "memory_add_physaddr_to_nid" [drivers/cxl/cxl_pmem.ko] undefined!
Fix this by exporting that function.
Fixes: 8c2676a5870a ("hot-add-mem x86_64: memory_add_physaddr_to_nid node fixup")
